In addition, the mechanism can provide a good supporting effect on the battery cell body by installing a buffer base at the bottom of the heat dissipation protection shell.

The heat dissipation cavity 201a can facilitate the heat dissipation of the battery body 1.

[0038] The operating process of this embodiment is as follows: during installation, the filter plate 201 is first connected to the positive pole seat 101 and the negative pole seat 102 through the connecting bolt 203, and then the substrate 301 is connected to the positive pole seat 101 and the negative pole seat 102 through the connecting bolt 203 to complete the connection and fixation of the positive pole seat 101 and the negative pole seat 102, and then the battery cell body 1 installed between the positive pole seat 101 and the negative pole seat 102 is fixedly connected.
